Using the funtion set_time_limit().It sets the number of
seconds a script is allowed to run .If this is reached
script returns a fatal error.The default limit is 30
seconds .If seconds is set to zero
no time limit is imposed.When called , set_time_limit()
restarts the timeout counter from zero.If the timeout is
the default 30 seconds,and 25 seconds into script execution
a call such as set_time_limit(20)
is made,the script will run for a total of 45 seconds
before timing out.
